Which is the external command?
Answer: D) No one
In MS-DOS, PATH, PROMPT, and VOL are all internal commands. They are built into the command interpreter (COMMAND.COM) and do not require separate executable files.
- PATH: Sets or displays the command search path.
- PROMPT: Changes the appearance of the command prompt.
- VOL: Displays the disk volume label and serial number.
Since all three are internal commands, none of the given options is an external command.
MS-DOS मा PATH, PROMPT र VOL तीनवटै Internal Commands हुन्। यी COMMAND.COM भित्रै समावेश हुन्छन् र चलाउन छुट्टै Executable File आवश्यक पर्दैन।
- PATH: Command खोज्ने Path सेट वा Display गर्छ।
- PROMPT: Command Prompt को स्वरूप परिवर्तन गर्छ।
- VOL: Disk को Volume Label र Serial Number देखाउँछ।
त्यसैले यीमध्ये कुनै पनि External Command नभएकाले सही उत्तर D. No one हो।
